CONCRYETE WINDOW CONSTRUCTION.

Specification of Letters Patent.

Patented Nov. e, 1906.

Application filed May 9, 1905. Serial No.' 259,563.

To a/ZL whom it may concern:

Beit known that I, FRANK B. GILBRETH, a citizenof the UnitedStates, residing'atv New York, in the borough of Manhattan, county and State of NewYork, have invented an Improvement in Concrete Window Construction, of which the following descri tion, in connection ,with the accompanying awings, is a speciiication, like letters on the drawings 1o re resenting like parts.

invention consists in improvements in 'buil g construction, and particularl in i providing awindoW-onstruction 'large y or wholly of concrete," thereby extending the I5 possibilities of ireproof concrete construction and eliminating all or a large part of the combustiblewoodwork heretofore employed 1n connection with Vwindow construction even on buildings otherwise constructed zo wholly of concrete.

My lnvention will be best understood by l reference to the following speciiicatipn,-

taken connection with the accompanying lllustratlon of one specific embodiment therez5 of, while its 'scopefwill be pointed out in the ap endedclaims.

yn the drawings, Figure 1 is an elevation, partially in section, showing one embodimento rmy invention in the form of an ordi- 3o nary vertically-slidable window-sash. Fig.

2y is'a section on the line 2 2 in Fig. l, and

Fig. 3 is a section on the line 3 3, Fig. 2.

In the drawings I have shown my inven- :tion asl embodied in up er and lower sashes p '35`a a of the conventiona rectangularsinglepanel type. `In the illustrated embodiment of mymvention each sash is formed of mold- "3, f edconcrete or; the like, any suitable metallic reinforcement, if desired, such as indicated at 4o b, being molded into each member of the sash when formed to give increased strength and rlgidit thereto. The vertical members of f, this `reinforcement may and do project above each sash at the sides thereof to present the exteriorly-exposed fastenmgfeyes c,-to1whch may be attached the weight-holding chains d, thereby connecting the sash-weights directly with the interiorlymolded reinforcement of the sash.

5o The glass-receiving portion of .the sash is formed to receive the appropriately-dimensioned pane e, there being formed, however,

preferably in the body of the sash a suitable crevice f or 'series of crevices to receive the usual glaziers points which are employed for temporarily the same in lace.

holding the glass in place I may and preferably do make use of concrete for this purpose, and in order that the same may have firm adherence when applied I form one or more. locking-grooves g in the body of the sash, so Ithat said grooves when applied for retaining the pane inposition. j

If the building to whicli my invention is applied is constructed of concrete, the sill of the material of the building itself. In the drawings I have shown the Window-jambs formed each of a separate" an' piece of concregef. These are designed to guide the sashes as the latter are-slidvertically up or down and for this purpose are provided with suitable vertical y-arranged grooves adapted to receive and fit the projccting vertical ribs k, formed on the sides of each sash. These ribs, as Well as all parts of the concrete construction, are molded with rounded edges to avoid the chipping or iracture of the material. Each jamb-piece carries at its upper end molded therein a pair of metal 'journals l, and on these are journaled the weight-rollers fm, over which pass the weight-chains d, carrying the weights lu., the latter being suspended' in a moldedl space formed between the lj amb-pieces and the material of the building.

tained in posltion in any desired manneras, for example, at the lower en by the Wedge or key piece o, which is forced into an ing placed in position may be adjusted somewhat to suitably it the window-sash and then iiXed in its adjusted position, either 're' movably so, or by-cementing, or in any other desired manner.

Instead o the putty usually ernployed'fo'r..

and lintel for the windowvma'y be molded out The jamb-pieces mayl be fitted and reolding glass in position before cementing i:

the concrete (shown at h) may enter into the f removable appropriately-molded opening, partly in the IOO After the jamb has been placed in position l it may be covered by theretaining member g,

also of concrete, partially overlying the lower sash and acting, therefore, in conjunction with the jambs and a corresponding overl g portion of the. building itself at the ont of the Window to serve as the window-frame. The retaining member g may be fitted into position by means of concrete wedges or keys 1 and when adjusted to a t may be cemented or otherwise fastened in place.

If desired,'the glass may be strengthened for ireproong or any other desired purpose by the interiorly molded reinforcement shown at S.

While I have herein shown one specific embodiment of my invention for illustrative `urposes, it is to be understood that it is not imlted to the details shown, but that many modifications may be made in the described embodiment thereof without departing from the spirit of my invention.
